Malaysia Airlines says in a statement that flight MH066 was diverted to the southern Chinese city after the main generator supplying normal electrical power failed. However, the jet’s auxiliary power unit was able to continue supplying power.

The airline said the 271 passengers bound for Incheon International Airport near Seoul were put on flights with other carriers.

Searchers are continuing to look for a Malaysia Airlines Boeing 777 that disappeared March 8 on an overnight flight from Kuala Lumpur to Beijing.
